[jdk8u-dev] RFR: 8069389: CompilerOracle prefix wildcarding is broken for long strings

[Roman Marchenko]

Clean backport.

I've just found that the issue occurs even with short strings like "*123*", see my screenshot attached to JDK-8069389. This can be reproduced currently with "slowdebug" build on my Ubuntu 22.04 + gcc-9.5.0, however I believe we cannot rely on it isn't reproduced with "release" now.

Anyway, it wasn't good to use "strcpy" with overlapped buffers, because strcpy's docs says "The behavior is undefined if the strings overlap." So, I believe it should be fixed in jdk8 as well.
